The results of Comove. HD 109833 and neighbors within 30 pc and 2 km s−1, are shown in X-, Y-, and Z-coordinates. The size of the points corresponds inversely to their distance from HD 109833, and the color with the velocity difference, so that the largest points are closest to HD 109833, and the darkest points are most similar in velocity. Stars with Gaia renormalized unit weight error (RUWE) ≥ 1.2 are represented with squares. The velocity differences of binary stars are poor indicators of membership, due to velocity from binary motion. Circles are used to represent stars with Gaia RUWE < 1.2.
